Installation of the Stability Module

Orientation of the Stability Module

The Stability Module may either be frame mounted to the trailer chassis or reservoir mounted . 
The following guidelines apply to either method of installation, tank or frame.

Regardless of the attachment method the orientation of the Stability module must be made 
known to the ITCM ECU for correct operation. The orientation may be configured with the 
DIAG+ Software or learned during the first trip of the trailer.

If the orientation is to be learned then the trailer must have at least two maneuvers performed.  
A straight-line stop of at least 30 mph at 30 PSI and a left or right turn. It does not matter if the 
turn is performed first or second.
